ATTACHMENT non News.

Application filed July 9, 1921. Serial No. 483,582.

To all who 17bit may concern:

Be it known that I, BURRIS E. I-Inrns, a citizen of the United States, residing at Corydon, in the county of lVayne and State of Iowa, have invented certain new and useful Improvements in Attachments for Plows, of which the following is a specification.

This invention relates to improvements in plows and the object is to provide a simple, practical and efficient device for preventing the accumulation of rubbish such as old straw, old stalks or weeds in front of the colter of the plow when plowing land con taining the same. This difiiculty is found particularly troublesome when it is attempt ed to run a plow through old straw stack bottoms, as the straw quickly bunches up in front of the colter, making further progress impossible without first removing the bunches and lifting the plow up until clear ground is again reached. The invention is more particularly described in the following specification and is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation of a gang plow, the right supporting wheel and other minor parts being omitted.

Fig. 2 is a plan View of the plow beam frame, showing the positions of the plows and colters relative to the parts embodying my improvement.

Fig. 8 is a fractional detail view showing a modification of the invention.

Referrin to the drawing by reference characters 3 designates a plow frame or carriage supported on wheels B and to which is secured a pair of plows G and corresponding colters, all of common and well known C011- struction. To the front part of the frame A (or to the forward end of each of the plow beams comprising the frame) I secure as at E a rearwardly inclined bar I one for each colter. The rear ends of the harsh extend back to within a short distance of the colters D and at a height substantially on a level with the colter centers. The bars are supported at said rear ends by brackets G which are bolted at their upper ends as at 'H to the plow beams, while their lower ends have angular projections J adapted to be bolted as at K to the bars F. In the event that the rear end of either of the bars F should need to be adjusted in order to bring it directly in front of the colter it is found desirable to first loosen the bolt K, then twist'the lower part of the bracket G slightly one way or the other. This will swing the projection J until the bar F is in the right position when the bolt K may again be tightened. In the modification shown in Fig. 3 this adjustment is made easier, as here the shank of the bracket G is round and is held in a socket L secured to the plow beam by bolts M, and by merely loosening said socket and the bolt I the bar F can be adjusted to and secured in any position found necessary.

It will be obvious with this construction in operation that the bar If will positively prevent the accumulation and bunching up of old straw or other matter in front of the colters, as all such matter will be gradually pressed down to the plowing level before being engaged by either the colters or the plows.

It is understood that suitable modifications may be made in the form and structure I 1. In combination with a plow beam having a plow and a colter secured thereunder, a rearwardly inclined bar secured at its front end to the plow beam and extending down to the colter at its rear end, a substantially vertical bra cket secured at its upper end to the plow beam so as to be rotatable relative thereto when so desired, an angular extension at the lower end of the bracket and a bolt adapted to secure said extension to the rear part of the bar, as set forth and described.

2. In combination with a plow beam having a plow anda colter secured thereunder, a rearwardly inclined bar secured at its front end to the plow beam and extending down to the colter at its rear end, a substantially vertical bracket having its upper end round and secured in a socket on the plow beam so as to be rotatable when so desired, an angular extension at the lower end of the bracket and a bolt adapted to secure said extension to the rear part of the bar.

In testimony whereof I afiix my signature.

BURRIS E. HAYES.
